4.General Motors acquired equipment used in its administrative activities for $ 100, 000 on January 1, Year 4. The equipment had an expected useful life of four years and zero salvage value. GM calculates depreciation using the straight-line method over the remaining expected useful life in all cases. On 12/31, year 4, after recognizing depreciation for the year, GM learns that new equipment now offered on the market makes the equipment GM purchased partially obsolete. The market value is now $ 60, 000. The expected useful life does not change. On 12/31, year 5, the market value of the equipment is $ 48, 000. GM sells the equipment on 1/1, year 7, for $26,000.

a. Assume for this part of the problem that GM accounts for equipment using acquisition adjusted for depreciation and impairment losses. Using the analytical framework described in the chapter, indicate the effect of the following events on the balance sheet and income statement. I. Acquisition of the equipment for cash on 1/1, Year 4 ii. Depreciation in Year 4 iii. Impairment loss for Year 4 iv. Depreciation for Year 5 V. Depreciation for Year 6 vi. Sale of the equipment on 1/1, Year 7

B. Assume for this part of the problem that GM accounts for equipment using current mar ket values adjusted for depreciation and impairment losses. Using the analytical framework described in the chapter, indicate the effect of the following events on the balance sheet and income statement. I. Acquisition of the equipment for cash on 1/1, Year 4 ii. Depreciation in Year 4 iii. Impairment loss for Year 4 iv. Depreciation for Year 5 V. Recognition of unrealized holding gain or loss for Year 5 vi. Depreciation for Year 6 vii. Recognition of unrealized holding gain or loss in Year 6 viii. Sale of the equipment on 1/1, Year 7
